# Build error in cordova-custom-config

### Incident

In the application build, an infinite loop occurs, resulting in the error "JavaScript heap out of memory".

### Cause 

The npm package "colors" was released with a bug that caused an infinite loop. The plugin "cordova-custom-config" also uses the npm module "colors", causing the bug.

### How to fix it 

The error has been fixed and "cordova-custom-config" v5.1.1 has been released. You can select the plugin version on the Cordova plugin settings page.

If the problem occurs with a plugin other than "cordova-custom-config", you can avoid using the version that contains the bug by modifying "package.json" in the root directory of the Monaca project as follows.

```
"dependencies": {
  ・・・
  "colors": "1.4.0",
  ・・・
}
```
